CYRUS A. TAFT, OF WHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WVHITINMACHINE \VORKS, OF SAME PLACE.

SEPARATOR FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 486,798, dated November22, 1892.

Application filed June 15, 1892.

To all whom it may concern.-

Be it known that I, CYRUS A. TAFT, of Whitinsville, in the county ofWorcester and State of Massachusetts, have invented a new and usefulImprovement in Separators for Spinning-Machines; and I hereby declarethat the following is afull, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification.

This invention has reference to an improvement in separators forspinning-machines in which a metal plate secured to a rocking shaft isplaced between two spinning-spindles to prevent the yarn of the twospindles from interfering with each other; and it consists in thepeculiar and novel device by which the motion of the separator iscontrolled and the machine adapted for spinning filling-yarn and windingthe same on a cop or bobbin in conical layers, as will be more fully setforth hereinafter.

The invention is applicable to all kinds of spinning-machines in whichthe separatorplates are secured to a rocking shaft. For the purpose ofillustrating the operation of the improvement it is shown in connectionwith the mechanism for operating the separators shown and described inPatent No. 365,155, granted June 21, 1887, to Gustavus E. Taft, for ayarn-separating device for spinning-machines.

Figure 1 is a vertical transverse section of a spinning-machine frame,showing the mechanism for operating the separator-plates and also themechanism by which the downward movement of the separator-plates iscontrolled so as to correspond with the building up of the cop. Fig. 2is an end view, and Fig. 3 a side view of the device by which themovement of the separator-plates is controlled.

In the modern spinning-machines the spindles are placed as closetogether as possible, and they are rotated at the highest possiblespeed. Under these otherwise desirable conditions the threads fromadjacent spindles are liable to interfere. To prevent this interference,separator-plates are placed between each pair of spindles. Theseseparators are required only when the ring-rail is on ,the lower portionof its Vertical traverse Serial No. 436,782. (No model.)

and in filling-frames only when the yarn is wound on the lower part ofthe spindle, cop, or bobbin, and then only while the yarn is wound onthe lower and larger diameter of the conical layers, for then only willtheyarn form balloons wide enough to interfere with each .other.

The objectof this invention is to arrest the motion of theseparator-plates as the cop is built upward and remove the separatorfrom between the spindles and out of the way of the ring-rail while theyarn is being wound on the upper part of the cop.

In the drawings, 4 indicates the frame of the spinning-machine; 5, thespinning-spindles; 6,the separator-plates; 7, the rock-shaft on whichthe separator-plates are secured, and 8 an arm secured to therock-shaft.

9 and 9are two levers, each pivoted on one of the arms 10, connected atthe outer ends with the arms Sand connected together at their inner endsby a pin secured near the end of one and extending through a slot in theother lever, so that the motion of one lever will be transmitted to theother. The lever 9' is connected by means of the rod 11 with one end ofthearrn12, pivoted at the other end in the bracket 13. The cam 14 issecured to a shaft and is driven by suitable gears, so as to revolveonce to every reciprocation of the ringrails 15. slightly more thancounterbalanced by the weight 16, so that the arm 12 will always bearagainst the cam 14. The weight 16 is connected by means of a cord orrope extending over a pulley 17 with the arm 9.

The mechanism so far described is the mechanism shown and described inPatent No. 365,155, abovereferred to; butany other mechanism or means bywhich the rock-shaft 7 is turned'to operate the separators can be usedin connection with my present invention, which I will now proceed todescribe more fully.

To the arm 8 I connect the rod 18, the lower end of which is adjustablyand pivotally secured to an adjustable stud-bolt in the slot 19, formedin the outer end of the arm 20, pivoted on the bracket 21. The short endof the arm 20 extends over the wedge 23, which slides in a groove formedin the bracket 21 The weight of the mechanism is and is held in place bythe screw-post 24, surrounded by a spiral spring.

25 is one of the rock-shafts used in spinning-machines to support thebell-crank levers used to reciprocate the ring-rails. The arm 26 issecured to the rock-shaft 25 and is provided with the curved slot 27, inwhich the pins 28 and 29 are adjustably secured. The wedge 23 isprovided with a lateral projection, against which the pins 28 and 29 canbear, and it is also provided with the lower extended surface 23, thestepped inclined surface 23 and the upper extended surface 23 Thepositions of all the parts when the separators are in position betweenthe spindles are shown in solid lines, and the positions when theseparators are raised and out of the way are shown in broken lines inthe drawings.

The operation of the device is as follows: When a spinning-machineadapted to spin filling-yarn and wind the same in conical layers on thespindle, cop-tube, or bobbin is started, the ring-rails are at thelowest of the vertical traverses. The ring-rails are raised and loweredby the bell-crank levers secured to the rock-shaft 25 to lay the yarn ina conical layer. At each downward motion of the ring-rails these arestopped at a point slightly higher, corresponding with the building upof the cop. This is done by means of the takeup mechanism connected withthe bell-crank levers secured to the shaft 25-an arrangement Well knownin the art of filling spinning-machines. The arm 26, being also securedto the shaft 25, moves with the bell-crank liftinglevers and the pin 28pushes at each greater oscillation the wedge 23 forward under the end 22of the arm 20, and this end of the arm is not arrested in its descentfirst by the straight portion 23, but is gradually more and morerestricted by the stepped portion 23 until when the upper half of thecop is reached and the separators are no longer required the end 22 ofthe arm 20 is arrested on the straight upper portion 23 of the wedge 23,so that the separators are held stationary until the cop is completed.When the cop is completed, the lifting mechanism or, as it is called,the copbuilding mechanism is wound back, the shaft 25 is thereby turnedto its original position and the pin 29, secured to the arm 26, engageswith the lateral projection on the wedge 23 and draws the wedge out intothe position shown in Fig. 3, ready to control the separators at thebuilding of the next cop. During the building up of the cops, while theend 22 of the lever 20 is over the flat portion 23 of the wedge, the cam14 continues to operate the separators, and as the stepped incline 23'is pushed under the arm end 22 more and more the descent of theseparators is resisted until when the flat portion 23 is under the end22 the separators and the actuating mechanism are held in the positionshown in broken lines in the drawings and the cam 14 revolves withoutaffecting the operation of the separators.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a spinning-machine, the combination, with thespindles, the ring-rail, and the mech-- anism for reciprocating thering-rail, so as to build the cops, of the rock-shaft 7, theseparator-plates6, secured to the shaft, the arm 8, also secured to theshaft 7, mechanism adapted to automatically vary the motion of theseparators, and means for oscillating the separators, as described.

2. In a machine for spinning filling, the combination, with thespindles,the separators, and the mechanism for operating the separators,of the ring-rails and the mechanism for reciprocating the ring-rails,the rock-shaft 25, the arm 26, the pins 28' and 29, the'wedge 23, thepivoted arm 20, and the rod 18, the whole adapted to limit theoscillation of the separators, as described.
